Indeed. Does tempest support hugepages/NUMA/pinning?
This is a running discussion, but largely no - because this is ited to the
capabilities of the host, there's no guarantee for a given scenario what result
you would get (because Tempest will run on any hardware).
If you have test cases that should pass or fail on a NUMA-capable node, can you
write them up? We're working on NUMA-specific testing right now (though I'm not
sure who, specifically, is working on the test case side of that).
I don't really have time to write up individual testcases right now, but I think
a good start would be to test the following features:
